OPAC (Online Public Access Catalog) is a computerized library catalog available to the public. Most OPACs are accsessible over the Internet to users all over the world.
Why use a catalog instead of just browsing the shelves of the library to find a book?
Books that contain information on a particular topic may be shelved in several different areas of the library, in special collections, or even in different libraries altogether.
Books are shelved in the library by call number order (a unique number for each book), so you would have to be very familiar with the either the Dewey Decimal or Library of Congress Classification System to find the small area devoted to your topic.
